, To all whom it concern.

'merchant, a subject of i mark, residing in the city of Copenhagen, a new and useful- Be it known thatl, ANTON FREDERIKSEN,

the King of Den- Denmark, have invented Improvement in Three-Pronged Safety-Pins,

which improvement is fully set forth in the following specification and accompanying drawings.

This lnvention relates to improvements in safety pins and is particularly designed for that class of pins wherein thepin shank is disposed between two members constituting a frame and wherein the ends of the frame members are provided with. a suitable form of shield or guard which also acts to control the pin point of the shank.

One of the objects ofmy invention is to provide a shield having a slit or opening for receiving the point of the pin shank and for holding the pin shank in a suitable normal position when disposed within the shield.

A further object is to provide such a shieldwith means for limiting movement of the hinge shank beyond a normal position so as to indicate to the'user that pressure on the pin shank in such site to the direction should be applied to the pin shank to release the same from the shield or guard through the slit therein.

The invention will be more fully described in connection with the accompanying drawing and'will be more particularly pointed out in and by the appended claim.

In the drawing :-Figure 1 is a plan view of'a safety pin embodying one form of my invention. Fig.2 is a sectional view on line A B of Fig. 1. Fig. 3 is an end view showing the in shank released.

Like 0 aracters of reference designate similar parts throughout the different figures of the drawing.

As shown the frame member's'and the pin shank are formed of a single length of material or wire and a shield or guard is provided at each end of the-safety pin, although it will be understood that I-do not wish-to a direction is oppoof movement which be limited to this specific constructiona -except for such limitations as the claim 1 im ports. l

Inthe form shownv the pin shank is des- Iignated at c and is disposed between two par allel members a and b constituting the frame. A guard'or shield e of the pin to incloseand-rigidly hold the members a, b and permit relative lateral shifting movement of the pin shank 0 with respect to the members a, and b. 'At the opposite end of the safety closes one end portion of the shank cand also the ends 0 the frame members a and The guard e is provided with an opening or slitg to permit "of removing and inserting thepin. point of theshank c therein. Thegopening or slit-g preferably disposed. laterall of the centerfof the guard e as shown. -C e ntrally of the guard e. a raised portion pin point of the shank c and the resiliency of the wire of which the shank c is composed is arranged to normally cause the pin point of the shank to enter. and engage the raised portion 7 and seat therein. Qn thatside of the center of the shield, opposite tdthe slit (7 the upper and lower portions of the shield c are brought together, preferably-by embed ding the 'upperportions at k. The spate between shield e at h is reduced. to such an extent that assage of the in point of the shank 0 there etween is'ren ered' impossible-so that when the user accidentally shifts the shank a in the wron direction to release the same from the shie d the shifting movement will be resisted and stopped and this will indicate 7 to the user that the shank is being shifted in the wrong direction. The operator willtheni shift the. shank in another direction and the same will be released through the openingg. I claim-:-

A safety pin comprising in combinatiomi' two parallel members constituting the frame,

a pm positioned centrally of pnd provided with a pin point and a shield atentedMay 31., 1910.
